Application of Probability in Maintenance

Good Day to everyone

Can anyone please help me, i'm a maintenance personnel (machines or engines).

We had a machine it could have two (2) events, first event is an ALARM-means it would not stop our machine, it just give warning to do something. Second event is we called it TRIP- means these would literary stop our machine, in short its a breakdown (loss).

I had counted totally our ALARM list it is 173 items and TRIP list is 168.

How could i present these mathematically- on probabilty? that this ALARM would appear
frequently, or this TRIP would appear frequently / these particular TRIP item would appear frequently.

Re: Application of Probability in Maintenance

Maintenance events are typically modeled using reliability methods. Trips and Alarms can be treated as two different failure modes, and Reliability numbers calculated separately for each. These can be expressed as a probability for survival (or failure) at a defined time.
